J OSEF ROSENBAUM, OF NUREMBERG, GERMANY.

APPARATUS FOR SAWING WOOD.

SPECIFICATION forming part of Letters Patent N 0. 733,278, dated July 7, 1903.

Application filed July 30, 1902.

To all whom it may concern.-

Be it known that I, J osnn ROSENBAUM, a subject of the Emperor of Germany, residing at Nuremberg, Bavaria, Germany, have invented cert-ain new and useful Improvements in Apparatus for Sawing Up Wood, of which the following is a specification.

This invention has for its object a machine which is intended for sawing or cutting wood, more particularly fire wood, into several pieces.

The machine is shown in the accompanying drawings, in which- Figure 1 is an end elevation of the machine; Fig. 2, a front view thereof; Fig. 3, a crosssection, and Fig. 4 a plan view, of the Worktable, and Fig. 5 a plan View of a fillingplate adapted to be inserted in the recess in the table.

The machine consists of a framework a. with a suitably-mounted shaft b, on which is a hand-rotated fiy-wheel or belt-pulley it. Several circular-saw blades 0 are fixed on the shaft 1) at suitable intervals apart.

In the under part of the frame a a worktable (1 with guide bars 6 is mounted on springs f. By means of a suitable treadle 9, connected with this table, the latter may be depressed against the action of the springs. The upper surface of the table is, as shown in Figs. 3 and 4, preferably made recessed or countersunk, so as to give more clearance for the saw-blades, and when necessary a fillingplate 1', Fig. 5, having grip or pin holes 70, may be inserted in this recess.

The wood Z is laid on the table 01 after the latter has been depressed and is brought Serial No. 117,634. (No model.)

within range of the action of the circular-saw blades 0 by releasing the treadle g, when the driving apparatus h is set in operation. In

order to support the wood, so as to counteract the side thrust produced by the working of the saw-blades c, struts n are provided on the table cl between the points at which the saw-blades work. The table itself is supported on the frame a to resist the thrust action of the saws by arms m, having rollers 0, which roll upon the frame-standards.

What I claim is- 1. In a wood-sawing machine, the combination with a frame and a gang of circular saws supported thereby, of a vertically-movable spring-supported table under the saws, substantially as described.

2. In a wood sawing machine, the combination with the frame and the circular saws supported thereby, of the vertically-movable table having arms with rollers bearing against the frame to resist the saw thrust, substantially as described. 7

3. In a wood-sawing machine the combi= nation with a frame and a saw supported thereby, of the vertically-movable table under the saw, guide-bars thereunder connected to a treadle, springs coiled around the guide bars and tending to raise the table, and arms projecting from the table having rollers traveling on the frame, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

JOSEF ROSENBAUM.
